N.Wood Posted September 20, 2006 Report Share Posted September 20, 2006 Possibility for water to boil down a long downhill?I know this isn't downhilling, but my Avid BB7 has become really hot during some places and its hot enough to start losing power.But whatever, water is thinner than mineral oil and will give it a lighter feel.I'd stick to mineral oil though to be honest.

powerz Posted September 20, 2006 Author Report Share Posted September 20, 2006 So the thinner the liquid the lighter the feel then.what about using DOT 4 ebc brake fluid,my dad uses it for his quad, would it be better than using water Quote Link to comment Share on other sites More sharing options...
mission man Posted September 20, 2006 Report Share Posted September 20, 2006 (edited) i was going to use dot 4 on my magura louise when it needs a bleed but people have told me not to as it wrecks the seals straight away. dont know if anyone can confirm this. but people also say that water wrecks the seals in the magura 33's but mine havent yet and ive bin running water for about 8 months. so try it prob be ok, if anything starts to happen with it start using mineral oil again.mission man Edited September 20, 2006 by mission man Quote Link to comment Share on other sites More sharing options...
The Duck Posted September 20, 2006 Report Share Posted September 20, 2006 Bleed it, with water, get all the air out, i had the same problem with my magura clara. If it doesnt work, keep bleeding it. Worked for my louise! But I think he means water and Anti-freeze, so it doesn't go icey in cold weather.Gurd luck! Quote Link to comment Share on other sites More sharing options...

tomtrials Posted September 20, 2006 Report Share Posted September 20, 2006 Dont say that,that will not be good I might take it down halfords and get them to give the brake a service.More Money Lol funny post. Best bet is to have a go yourself go on google and search how to bleed the brake like the other guys have said it is alot better to bleed with water and it is alot less messy. the only really downside is that water will freeze in cold temperatures.

lawrence osborn Posted September 22, 2006 Report Share Posted September 22, 2006 Ive cracked a magura at the bleed screw from tightening it to much :$ also your disk does get amazingly hot, one day me and a few mates was out riding and there was this twat watching us from the bottom of this big hill shouting questions at us, so we decided to go and see what he wanted and my mate went down the hill fast with his disk brake on, when we got to him my mate said to this twat guy push my disk over a bit mate, and this guy push his disk and it burned his fingers Quote Link to comment Share on other sites More sharing options...
